British spelling. No googling!

Multiple choice answers. Good luck


Question 1

There are over 200 moons orbiting planets in the solar system.

What moon is the largest?

(Titan, Ganymede, or Callisto)


Question 2

Olympus Mons is an inactive volcano on Mars.

How high is Olympus Mons?

(8.9, 15.9, or 21.9 kilometres)


Question 3

Comets are snowballs of gas, rock, and dust that orbit the sun.

One of the most well-known is Halley's Comet.

When will Halley's comet return and be visible in the night sky again?

(2041, 2051, or 2061)


Question 4

What is the highest recorded natural surface temperature on Earth?

(53.7, 56.7, or 59.7 degrees Celsius)


Question 5

Proxima Centauri is a star that is nearest to the sun.

How far is Proxima Centauri from the Sun?

(2.3, 3.4, or 4.2 light-years)


Question 6

Water covers over 70% of the Earth's surface and is very deep in certain places.

What is the deepest part of any ocean?

(6, 11, or 15 kilometres)


Question 7

At any one time, the atmosphere of the Earth holds an astonishing amount of water.

Roughly, how much water is there in the Earth's atmosphere?

(6,900, 12,900, or 16,900 cubic kilometres)


Question 8

UY Scuti is arguably the largest star known at this time. The sun has a diameter of 1.3927 million kilometres.

What is the diameter of UY Scuti?

(1.3765, 2.3765, or 3.3765 billion kilometres)


Question 9

As you know, the sun is much larger than Earth, but by how much?

By volume, how many Earths could fit inside the Sun?

(1.3, 1.9, or 2.1 million Earths)


Question 10

The space probe Voyager 1 was launched into space in September 1977 and is the most distant object that has ever left our planet.

As of January 2024, how far from the Earth is Voyager 1?

(8, 16, or 24 billion kilometres)

Answer to Question 1: Ganymede

Ganymede, a satellite of Jupiter, has a diameter of 5,270 kilometres, making it larger than our Moon.


Answer to Question 2: 21.9 kilometres

Olympus Mons is the highest volcano in the Solar System; as a comparison, the highest mountain on Earth, Mount Everest, is 8.8 kilometres high.


Answer to Question 3: 2061

When comets come close to the sun, they warm up and produce a glowing tail, which can be seen in the night sky. Halley returns to Earth every 75 years, so depending on when you were born, some will see it twice in their lifetime. I saw it in 1986, but I will never see it again.


Answer to Question 4: 56.7 degrees Celsius

That temperature was recorded in California's Death Valley way back in 1913.


Answer to Question 5: 4.2 light-years

Proxima Centauri, the Sun's closest star neighbour, may seem very close at just 4.2 light-years. But remember, for every second of those 4.2 years, the light leaving that star will have travelled 300,000 kilometres towards us.


Answer to Question 6: 11 kilometres

The deepest part of any ocean is the Challenger Deep, located in the Mariana Trench at the bottom of the Pacific Ocean.


Answer to Question 7: 12,900 cubic kilometres

The amount of water held in the atmosphere is very small compared to the total amount of water on Earth, which is estimated to be 1,358,000,000 cubic kilometres.


Answer to Question 8: 2.3765 billion kilometres

We think our sun is massive, but it is minuscule compared to UY Scuti.


Answer to Question 9: 1.3 million Earth's

Yes, the Earth is very small in comparison to our local star, the Sun.


Answer to Question 10: 24 billion kilometres / January 2024

As of January 2024, Voyager 1 keeps moving away from the Earth at over 60,000 kilometres per hour. Maybe in the distant future, some other life form will find it. That is, of course, if there is intelligent life somewhere out there in the unknown.

The end.

    That is amazing that 1.3 billion earths can fit in to the sun. Wow! I am also intrigued by Voyager 1 how far away from Earth that keeps moving and thus far has not come in contact with any other intelligent life form. Or has it?
